Software Development Services in San Diego

When your business needs custom software — not off-the-shelf tools that almost fit — you need a development team that understands both the technology and your business.

Resultris is a San Diego-based software development company that builds web applications, mobile apps, APIs, SaaS products, and AI-powered solutions for businesses across San Diego and beyond. We combine modern development practices with a clear understanding of what your business needs to succeed.

What We Build

Web Applications

Custom web-based software including client portals, dashboards, booking systems, internal tools, and business automation platforms. Built with modern frameworks for speed, security, and scalability.

Mobile Applications

iOS and Android apps using cross-platform technology that lets us build for both platforms efficiently. From customer-facing apps to internal workforce tools.

API Development and Integration

Custom APIs that connect your systems, enable third-party integrations, and power your applications. RESTful and GraphQL APIs built with security and documentation as priorities.

SaaS Products

End-to-end development of software-as-a-service products, from MVP to scale. Multi-tenant architecture, subscription billing, user management, and everything else SaaS products need.

AI Development and Integration

Practical AI solutions including LLM integration, automated workflows, intelligent document processing, and custom AI-powered features for your existing products.

Software Modernization

Upgrading legacy systems to modern technology stacks. Whether you're migrating off an aging platform or rebuilding a critical system, we handle the transition without disrupting your business.

Team Augmentation

Experienced developers who integrate with your existing team to accelerate development. Flexible engagement models from short-term projects to ongoing support.

Application Maintenance and Support

Ongoing support, bug fixes, performance optimization, and feature development for your existing applications. We keep your software running smoothly so you can focus on your business.

Our Technology Stack

We work with modern, proven technologies:

• Frontend: React, Next.js, Astro, TypeScript, Tailwind CSS
• Backend: Node.js, Python, PostgreSQL, Redis
• Mobile: React Native, Ionic
• Cloud: AWS, Google Cloud, Vercel, Netlify
• AI/ML: OpenAI, Anthropic Claude, custom model integration
• DevOps: Docker, CI/CD pipelines, automated testing

We choose the right tools for each project rather than forcing everything into one stack.

How We Work

1. Discovery. We invest time upfront to understand your business, your users, and the problem you're solving. This prevents expensive mid-project pivots.

2. Planning. We create a detailed project plan with clear milestones, deliverables, and timeline. You know exactly what you're getting and when.

3. Iterative development. We build in sprints, delivering working software regularly so you can see progress, provide feedback, and course-correct early.

4. Quality assurance. Every feature is tested before delivery. We write automated tests, perform code reviews, and conduct thorough QA to ensure reliability.

5. Launch and support. We handle deployment, monitoring, and post-launch support. Your software launch is the beginning of the relationship, not the end.
